Windows Server Backup in SBS2008 shows recovery restored successfully but may be corrupt

I have in SBS 2008 server configured with three volumes (3 arrays) C, D and E
my E Drive Is my data Drive. I needed to increase the storage capacity by doubling the size of the DATA drive
- I performed a full backup of the entire server using the built-in Windows server backup.
- Shut down the server and removed the four 72GB SAS drives (in Raid 5) and installed four 146GB SAS drives. Reconfigured the array successfully and re-mounted the volume with the same drive letter.
- Using Windows server backup, I performed a recovery by choosing the volume.
- After a few hours, I confirmed that the recovery was successful however with a warning that stated the recovery may be corrupt.
- From the server I was able to open all the folders and confirmed file security
- however from a workstation, all the mapped drive letters were inaccessible.
- The warning stated that I could either try a different recovery from a different backup or perform CHKDSK. I ran the CHKDSK from the drive properties > Tools > Check Now. I did not place a check in the 2nd box (which would indicate “CHKDSK /R”. I did not perform this from an elevated CMD prompt. When completed, The workstations still could not open any of the drive letters
- I rebooted the server. After rebooting the server, users could access all of the folders under the drive

- From a workstation, I was able to see all of the folders on the data Drive
- My question: should I run the CHKDSK /R from a CMD prompt? My concern is that the original report stated that it all the corrupted files to a folder on the drive but I could not find that folder.

I would perform another backup and then run the checkdisk /r from the elevated command prompt to be sure the disk is in working order. Don't worry too much about finding the corrupted files - often they

I would perform another backup and then run the checkdisk /r from the elevated command prompt to be sure the disk is in working order. Don't worry too much about finding the corrupted files - often they are just remnants of temporary or deleted files anyway. And don't overwrite your old backup just yet, until you find out if anything is really missing.

I've already started a CHKDSK /R from an elevated CMD prompt. Its been running for around 20 minutes.

I did not want to do a restore from the previous night's backup for obvious reasons.
If data is missing, I could reinstall the original drives for they should retain the Raid5 info and then do another backup.

Using the Windows server backup to perform the restore, would there be any benefit to just restoring all of data by restoring all the folders instead of choosing the option to restore the entire volume? The only downside would be having to reapply permissions. I also do a nightly backup using MozyPro to the cloud but it's backup was from the night before.

What's ironic, is the fact that the manual backup I kicked off in Windows server backup was successful but restoring it was also successful with errors indicating that it may be corrupt - as I mentioned earlier in this post.

You don't need to run CHKDSK /r on RAID configuration. The /f key is enough.
It could be that some of crosslinks were not in order and the chkdsk fixed it. As long as everything is working stay calm and continue using the server.
